Factors controlling the selenium-induced cyclizations of alkenyl hydrazines to pyridazine or pyrrolidinamine derivatives

Add time:08/10/2019    Source:sciencedirect.com

4-Pentenyl hydrazines, CH2CHCH2CH2CH2NHNHR, react with phenylselenenyl sulfate, produced by diphenyl diselenide, ammonium persulfate and trifluoromethanesulfonic acid, to afford phenylseleno-substituted hexahydropyridazine or pyrrolidinamine derivatives depending on the nature of the substituent R.
